A 4K gaming monitor is the ultimate way to experience your favorite PC games. The enhanced resolution provides incredible sharpness that brings out details you’d miss at a lower resolution. Distant objects that were once a blurry mess become clear as day because these displays are showing four times the resolution of a 1080p gaming monitor.
Buying a 4K gaming monitor is an investment, however, as most models are at least $500. You may spend several times that for a high-refresh display that supports both AMD FreeSync and Nvidia G-Sync. We’ve compared dozens of options to find the best 4K gaming monitors available right now – and click here to find them in the UK.
TL;DR – These are the Best 4K Gaming Monitors:
- Acer Nitro XV282K
- Samsung Odyssey G70B
- Gigabyte M28U
- Sony Inzone M9
- Asus ROG Swift PG32UQ
- Asus ROG Swift PG32UQX
- LG UltraGear 48GQ900
Acer Nitro XV282K
Best 4K Gaming Monitor
The Acer Nitro XV282K is an easy recommendation among the current crop of 4K gaming monitors. It hits a value sweet spot by providing a high maximum refresh rate, multiple HDMI 2.1 ports, and great image quality for less than $1,000. This is an IPS monitor with a refresh rate that can overclock up to 170Hz. Motion clarity is excellent and AMD FreeSync is supported. G-Sync support is not official, though we tested the monitor with G-Sync and found it worked without flaw.
The monitor’s contrast ratio is high for an IPS panel. A wide color gamut and great color accuracy provide a vivid, lifelike picture. It’s a bright display, as well, with a sustained peak of 400 nits. Most games look stunning. Build quality is modest, though fine. The stand looks unimpressive but adjusts for height and keeps the display stable. Around back you’ll find two HDMI 2.1 ports and DisplayPort, while USB-A ports are available for adding wired peripherals.
Samsung Odyssey G70B
Best Budget 4K Gaming Monitor
For a monitor that lets you game in 4K at 144Hz without breaking the bank, there’s nothing better than the Samsung Odyssey G70B. You’ll enjoy those super smooth frame rates and 1ms response time while your graphics card and display remain on the same team, thanks to both G-Sync compatibility and FreeSync Premium Pro support, preventing stuttering and screen tearing. And you aren’t limited to just hooking up a PC, as it's packing two HDMI 2.1 inputs in addition to a DisplayPort 1.4, so you can take advantage of the gaming features on the latest consoles, too.
While gaming, you’ll enjoy watching the action on a large 32-inch monitor with an IPS panel that offers solid viewing angles. And though the Samsung Odyssey G70B may not be the brightest display around, hitting 300 nits, it still has DisplayHDR 400 for decent contrast and deep blacks to uncover enemies hiding in the shadows. You’ll also appreciate the highly adjustable stand that can swivel, tilt, and even pivot a full 90 degrees to be in portrait mode.
Gigabyte M28U
Best Ultra-Cheap 4K Gaming Monitor
The Gigabyte M28U is perfect for gamers who don’t have a ton of cash but still want a 4K monitor with a high refresh rate, as it offers both at price far lower than most alternatives. The 144Hz refresh rate and Free Sync support hold up in fast-paced games. It even supports multiple HDMI 2.1 inputs to hook up a PS5 and Xbox Series X, while a USB-C and three USB-A ports are handy for other peripherals.
You’ll enjoy a colorful, accurate image with excellent sharpness on this ultra-cheap monitor. The catch? Brightness. At 300 nits sustained, the M28U could seem dim when used in a bright room. While the overall build quality is inoffensive and basic though you do get an adjustable stand for better viewing.
Sony Inzone M9
Best 4K FreeSync Gaming Monitor
The Sony Inzone M9 might be the brand's first monitor in years, but delivers some of the best HDR gaming we’ve ever seen. Not only does it feature a 600-nit peak brightness that's higher than most of its competition, but it also features 96 lighting zones to help drive better contrast so you can see pure darkness right next to blinding light. This gaming monitor can even self-tune its HDR capabilities when connected to a PS5 thanks to its Auto HDR Tonemapping feature.
This screen also has everything you want including a 4K resolution, 144Hz maximum refresh rate, FreeSync and VRR support, plus one DisplayPort and two HDMI 2.1 ports. It also looks as good as the picture it delivers with a modern white and black design that’s clean and maybe a bit PS5-inspired. For $900, this 4K gaming monitor delivers in every way and the only thing it lacks is video cables in the box.
Asus ROG Swift PG32UQ
Best 4K G-Sync Gaming Monitor
The Asus ROG Swift PG32UQ is among the few 4K gaming monitors with official G-Sync support. It’s a solid gaming display with awesome HDR performance. Image quality is better than average. The monitor supports a wide color gamut and has high color accuracy. It beats most competitors in brightness, hitting up to 600 nits in HDR mode. This provides punchy visuals when playing HDR games.
Motion clarity is great thanks to the 144Hz refresh rate and official G-Sync compatibility. Unlike many competitors, this monitor is listed on Nvidia’s website as officially certified. Build quality is a highlight. This is a large, sturdy monitor that looks and feels durable. The height-adjustable stand is among the most stable you’ll find. The monitor supports HDMI 2.1, DisplayPort, and has two USB-A ports.
Asus ROG Swift PG32UQX
Best 4K HDR Gaming Monitor
The Asus ROG Swift PG32UQX is a nearly unbeatable gaming monitor. It serves up 4K sharpness with a dynamic Mini-LED backlight with 1,152 zones that can turn on and off independently. This helps the PG32UQX deliver a contrast ratio four times better than an average gaming monitor with an IPS panel. It can also hit a peak brightness of 1,400 nits and sustain about 600 nits, making it a killer HDR display. Color gamut and accuracy are class-leading, too.
The monitor has a 144Hz refresh rate. It supports AMD FreeSync and G-Sync Ultimate, which means it can provide smooth frame pacing even at low frame rates. Its IPS panel is not the most responsive, though, so you may see ghosting at times.
Build quality is excessive. This is a massive, hefty monitor that’s overkill for most gaming setups. It has unusual extras like a tripod mount for a webcam and a small LCD display that can show extra information like game framerate. Console gamers should note this monitor does not support HDMI 2.1. However, it can achieve 120Hz gameplay on Xbox Series X|S models through a chroma subsampling mode. It can only display 60Hz with a PlayStation 5.
LG UltraGear 48GQ900
Best Big Screen 4K Gaming Monitor
The LG UltraGear 48GQ900 is essentially everything we love about the latest LG C2, but turned into an oversized gaming monitor. Of course, with an OLED panel, you get all the benefits of true blacks, infinite contrast, and eye-popping color. That OLED panel also lends you plenty of gaming benefits including an incredibly low 0.1ms response time while displaying incredibly smooth motion.
Unlike its gaming TV equivalent, the LG UltraGear 48GQ900 comes with a narrower monitor stand, an anti-reflective finish, and a handy remote for changing inputs and settings. Lastly it features a refresh rate of 120Hz (or 138Hz while overclocked), and it supports AMD FreeSync Premium Pro and G-Sync compatibility.
Where to Get the Best 4K Gaming Monitor in the UK
What you need to look for in a 4K Gaming Monitor
4K is pushing the limit of what’s possible on a typical gaming PC, so 4K gaming monitors don’t support some features found at other resolutions. For example, you won’t find any 360Hz or 240Hz gaming monitors that output at Quad HD. Most models aren’t great at HDR, either, with a few exceptions noted on this list.
All 4K monitors produce a sharp image, so you’re pretty much free to choose a screen size as big as you want and your budget will warrant. Because the pixel density is so tight you generally want to pick a display that’s at least 27 to 32 inches. And if you really want to go big, we generally feel that you can’t see the individual pixels of a 4K screen until you get up to a 65 inch.
Conversely though, sharpness generally improves as the size of a display decreases. The same number of pixels are packed in a smaller space. A 27-inch or 28-inch 4K monitor will be sharper than a 32-inch monitor, which will appear sharper than a 43-inch or 48-inch alternative. The difference is minor but worth considering if image clarity is your top priority.
Most 4K monitors use an IPS display panel that offer a lackluster contrast ratio. The good news is they also sport high brightness, great motion clarity, and accurate color. A rare few alternatives use a VA panel. This type of display boosts contrast ratio and retains good color performance, though often at the cost of motion clarity in dark scenes.
Gamers should keep an eye out for new models with a Mini-LED backlight. This pairs an IPS panel with an array of LED dimming zones to improve contrast. Mini-LED monitors deliver eye-searing HDR, as well. So far, there’s only a handful of Mini-LEDs options on the market, but they’ll become more common in the near future.
OLED is mostly exclusive to the television market for now. A few 4K OLED monitors are available, such as the LG 32EP950-B, but they’re extremely expensive and target professional media production instead of gaming.
Most 4K gaming monitors max out at a 144Hz refresh rate, though some slightly exceed that with an overclocking mode. This might seem disappointing at a glance. 4K gaming places a heavy load on a gaming PC, however, so many games will fail to constantly hit 144 frames per second, nevermind 240 FPS or more.
All the monitors on this list support AMD FreeSync or Nvidia G-Sync, and some support both. Nvidia fans should note that monitors which do not officially support Nvidia G-Sync may still work with Nvidia video cards. If you want a monitor with a G-Sync module, however, check out our round-up of the best G-Sync monitors.
